The prime minister's official spokesman said the government will respond to thebank holiday proposal "in due course" but added that extra bank holidays "come with economic costs".

Samantha Richardson, director at the National Coastal Tourism Academy, said 7% of businesses in coastal communities have closed permanently and that estimates suggest as much as 25% of accommodation will be lost along the coast as a direct result of the pandemic.

Specific assistance is needed for seasonal tourism businesses that earn their money between March and October, she said, suggesting they are looking at "three winters in a row".

She said: "We've lost the 2020 season, effectively. And we are going to need help to get through to next spring. So I think the winter is when we will see businesses fail without that support."
